Hope Cooke, the former Queen of Sikkim

In 1989, Oprah Show viewers met Hope Cooke, a woman once known as "the intellectual's Grace Kelly." Raised in a prominent New York family, Hope met and married the crown prince of Sikkim, a small Himalayan country that bordered India, Nepal and Tibet. When Sikkim was annexed into India in 1975, the king lost his crown, the couple separated and Hope returned to America to raise their two children.
